ROCK-DRILLING MACHINE.

Specification of Letters Patent.

Patented Mar. 3, 1914.

Application filed September 9, 1910. Serial No. 581,197.

To all whom it may concern:

Be it known that I, CHARLns C. HANSEN, a citizen of the United States,and resident of Easton, in the county of Northampton andv State ofPennsylvania,'have invented new and useful Improvements in Rock- DrillinMachines, of which the following is a speci cation.

This invention relates to that class of rock drilling machines in whicha suitable support, such, for instance, as a wagon, is pro vided with aframe uprising therefrom,

along which frame a rock drill or other tool is movable toward and awayfromits work.

The object of this resent invention is to provide means for ositivelymoving the tool toward and away from its work by the medium of asuitable motor, means also being an a ,A suitable reversing engine 4 isprovided for propelling 1 gine and the pa r of traction wheels 3 com-..

provided for exerting a tension on the toolto hold it firmly against itswork.

tendin By t e provision of the proper means for carrying out the aboveobjects, the use of weights for feeding the tool to its work isobviated.

In the accompanying drawings, Figure 1 is a front view of one form ofrock drilling machine with my improvement applied thereto, Fig. 2 is aside view of the same, partly in section, Fig. 3 is a top plan view ofthe form shown in Fi s..1 and 2, and Fig. 4 is-a partial side view 0 amodified form in which a turntable is provided for carrying the drillframe.

Proceeding to describe the form shown in Figs. 1, 2 and 3, the wagonframe is denoted by 1 and its pairs of traction wheels by 2 the wagon.in either direction, the driving connection between the enprlsing a gear5, pinion 6, sprocket wheels 7 8, 9, 10, their chains 11, 12, and thegear and pinlon connection '13, '14. Power is supplied to the engine 4through the pipe 15 from 'any suitable source of power,-not

' shown herein.

-A drill frame uprises from the wagon frame 1, the upright members ofwhich frame are denoted by 16, between which the rock drill 17 is fittedto slide toward and awa from its work. 7 ..T is rock drill is positivelmoved toward and away fr'oindtswork roviding. a

iteeding cable18 and a withdrawing cable 19,

turntable.

the cables being so led that as one is wound on the winding drum, theother will be unwound therefrom. The cable 18 leads downwardly along theside members 16 of the drill frame and passes under a fixed pulley 21,thence over a pulley '22 of a tension device and from thence under afixed pulley 23 from. which it passes to the winding drum 20.

Tension is applied to the feeding cable 18 to take up all slack thereonand to hold the rock drill firmly to its work. This is accom plished, inthe present instance, by mounting the pulley 22 on the end of a,piston24: operatin in a cylinden25 to which pressure fluid is ed through a pe26 leading to a source of pressure flui herein. v

The withdrawing cable 19 leads upwardly from the rock drill along theside members 16 of the frame and passes around a fixed pulley 27 fromthence it passes downwardly to the winding drum 20. l

A Windlass 28 is shown on the frame for controlling the movements of alifting cable 29 which passes upwardly around a fixed pulley 30, thencedownwardly to a suitable point for attachment to the drill steel 31 forhandling the same.

A branch pipe 32 leads from the motive fluid pipe 26 to the Windlass 28.

A branch pipe 33 leads from the pipe 32 to the rock drill 17 forsupplying the motive fluid thereto.

In the form shown in Fig. 4, a turntable 34 is mounted on a track 35carried by the wagon and the drill frame uprises from this Suitableclamps 36 are provided for securing the turntable in its different 19through the center of the turntable and from thence back to the drum20.- In other supply, not shown respects the parts of the machine arequite similar to those already described in connection with the formshown in Figs. 1, 2 and 3.

' While I have chosen to show and describe my invention in connectionwith a rock drill, it is obvious that a tool of any character 'might beused without departing from the scope of the invention.

It is also evident that changes might be resorted to in the form,construction and nections between arrangement of the several partswithout departing from the spirit and scope of my invention; hence I donot wish to limit myself strictly to but hat I claim is:

1. A wagon, percussive tool engine carried by the wagon, flexible contheengine and tool whereby the tool is moved positively along the frametoward and away from its work and means for operating the tool.

2. A wagon, a turntable thereon, a frame uprising from the turntable, apercussive tool movable along the frame, an engine carried by the Wagon,flexible connect-ions between the engine and tool whereby the tool ismoved positively along the-frame toward and away from its work and meansfor operating the tool.

3. A wagon, a frame carried thereby, a percussive tool movable along theframe, an engine carried by the wagon, flexible connections between theengine and tool whereby the tool is moved positively along the thestructure herein set forth,

' tool.

a frame carried thereby, a movable along the frame, an

from its worli, a the flexible conmove the tool toframe toward and awaytension device engaging nection which operates to ward its work andmeans 7 4. A suitable support, a frame carried thereby, a percussivetool movable along the frame, means for positively feeding andwit-hdrawin the tool along the frame, a tension device or the feedingmeans and means for operating the tool.

5. A suitable support, a frame carried for operating the thereby, apercussive tool movable along the frame, tool feeding and withdrawingcables, means for operating them, a tension device engaging the feedingcable, and means for operating the tool.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two witnesses, this first dayvof September, 1910.
